Definitions
- the present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner having a cyclone dust collecting apparatus matingly disposed along a connection pipe, and capable of filtering out and collecting relatively large particle contaminants from dirt-laden air drawn in through a suction port.
- a vacuum cleaner has a cleaner body 1 , a connection hose 2 connected to the cleaner body 1 , an extension pipe 3 connected to connection hose 2 and a suction port 4 connected to an end of the extension pipe 3 .
- a cover 5 is pivotally mounted on cleaner body 1 , and cover 5 is connected to connection hose 2 .
- Cleaner body 1 has a dust collecting chamber 6 inside.
- a paper filter 7 is removably received in chamber 6 to collect contaminants such as dust which are vacuumed through suction port 4 .
- a handle grip 8 is provided between connection hose 2 and extension pipe 3 . The handle grip provides a location for a user to easily manipulate extension pipe 3 and thereby guide suction port 4 during the cleaning operation.
- the vacuum cleaner also includes a motor (not shown) mounted in the cleaner body 1 to generate a suction force to draw in dirt-laden air through suction port 4 .
- the dirt-laden air is drawn into cleaner body 1 via extension pipe 3 and connection hose 2 .
- Solid contaminants are filtered at paper filter 7 that is disposed in the dust collecting chamber of the cleaner body 1 , while the exiting air is discharged outside of the cleaner body 1 .
- a vacuum cleaner having a cyclone dust collecting apparatus 10 has been suggested.
- a cyclone dust collecting apparatus serves as a first stage filtration area so the filter in body 1 can serve as a second stage filtration area.
- the collected debris in the cyclone dust collecting apparatus can be simply dumped without the use of disposable filters.
- the cyclone dust collecting apparatus 10 is connected and thus disposed at a part of the extension pipe 3 that connects the cleaner body 1 and the suction brush 4 .
- Cyclone dust collecting apparatus 10 includes a cyclone body 20 having first and second connection pipes 11 and 12 , respectively, a dust collecting receptacle 30 removably connected to cyclone body 20 , and a filter member 40 positioned in dust collecting receptacle 30 .
- the first connection pipe 11 is connected to extension pipe 3 ′ proximate suction port 4 and second connection pipe 12 is connected to extension pipe 3 ′′ proximate cleaner body 1 .
- Dust collecting receptacle 30 has a substantially cylindrical shape. Dust collecting receptacle 30 can also have a shape of a tapered cylinder which grows narrower as it extends downward.
- dirt-laden air drawn in through the suction port 4 , is drawn through an air inlet 11 a of first connection pipe 11 into the cyclone body 20 in a diagonal relation with respect to cyclone body 20 .
- an air vortex is generated in cyclone body 20 and dust collecting receptacle 30 in a direction indicated by the solid-lined arrows in FIG. 2 .
- a centrifugal force is generated, separating large particle contaminants from the air.
- the separated contaminants fall and then are entrained in an upturning air current (indicated by the dot-lined arrows of FIG. 5 ) and then reflected from the bottom of dust collecting receptacle 30 .
- the separated contaminants are discharged toward the cleaner body 1 through an air outlet 12 a formed in the cyclone body 20 .
- filter member 40 within receptacle 30 prevents the contaminants from reversing together with the air flowing through air outlet 12 a of cyclone body 20 during the operation of cyclone dust collecting apparatus 10 .
- the vacuum cleaner having such a cyclone dust collecting apparatus 10 is constructed such that the large particle contaminants of the dirt-laden air drawn in through the suction port 4 are pre-filtered in the cyclone apparatus before the dirt-laden air flows to the paper filter 7 .
- the cyclone apparatus functions as a first stage filtration device, and the air exiting the apparatus is directed to paper filter 7 to undergo an additional filtration step. Accordingly, the amount of contaminants to be filtered by paper filter 7 decreases, and the lifespan of paper filter 7 is lengthened. Also, by pre-filtering large particle contaminants, other advantages like prevention of suction force deterioration and motor overload are expected.
- the rather bulky volume of the cleaner is cumbersome, and a user often finds it tiresome to use the cleaner and to move it as necessary during the cleaning operation.
- the present invention has been made to overcome the above-mentioned problems of the prior art. Accordingly, it is an object of the present invention to provide a cyclone dust collecting apparatus for use in a vacuum cleaner having a reduced size.
- Another object of the present invention is to provide a cyclone dust collecting apparatus which facilitates easy manipulation for a user to carry the same during a cleaning operation.
- the cyclone dust collecting apparatus for use in a vacuum cleaner includes many of the same features as the vacuum cleaner described above the dust collecting receptacle is positioned along side the connection pipe, with the connection pipe having a shape that matingly follows the outer surface of the dust collecting receptacle.
- the dust collecting receptacle has a generally cylindrical shape so that in a horizontal sectional view its profile is substantially circular.
- the side of the connection pipe proximate the receptacle is contoured to correspond to the outer side of the cylindrical dust collecting receptacle.
- the cross-section of the connection pipe is substantially rectangular with a contoured side that is concave to matingly accommodate the circular profile of the receptacle.
- the overall width of the extension pipe and the dust collecting receptacle is reduced by this mating geometry, and accordingly, the vacuum cleaner is more compact and easier to manipulate, carry and use.
- the cyclone dust collecting apparatus also has a handle formed on the cyclone body.
- the handle is integrally formed with the cyclone body. Accordingly, the user can grip the handle, and perform the cleaning operation or carry the cyclone dust collecting apparatus with ease.
- FIG. 1 is a perspective view of a vacuum cleaner with a conventional cyclone dust collecting apparatus
- FIG. 2 is an enlarged sectional view of the cyclone dust collecting apparatus of FIG. 1 ;
- FIG. 3 is an exploded perspective view of a cyclone dust collecting apparatus according to the present invention.
- FIG. 4 is a view of the cyclone dust collecting apparatus of FIG. 3 assembled.
- FIG. 5 is a cross-section taken on line I—I of FIG. 4 .
- FIGS. 3 through 5 A preferred embodiment of the present invention will be described in greater detail with reference to FIGS. 3 through 5 .
- the description will focus on the novel aspects of the present invention with reference to the vacuum cleaner described above for aspects in common with the present invention.
- the location of elements of the vacuum cleaner will be described with respect to the one-directional airstream or suction force.
- extension pipe 103 ′ is upstream of cyclone body 120
- connection hose 103 ′′ is downstream of cyclone body 120 .
- the cyclone dust collecting apparatus includes a first member 111 and a second member 112 , constituting a cyclone body 120 in cooperation with each other, a filter member 140 is disposed in second member 112 , and a dust collecting receptacle 130 is formed at a lower portion of second member 112 .
- a connection pipe 111 b is provided on an upper portion of first member 111 connecting to connection hose 103 ′′ that is connected with the cleaner body. At an end of connection pipe 111 b , a discharge outlet 111 a is formed.
- a connection pipe 112 b is formed on second member 112 , having a suction inlet 112 a formed at an end thereof. The connection pipe 112 b is connected to extension pipe 103 ′ that is connected to the suction port of the vacuum cleaner.
- Filter member 140 is disposed in second member 112 , and dust collecting receptacle 130 is held at the lower portion of second member 112 by a fastening member 131 .
- the air drawn in through the suction inlet 112 a of cyclone body 120 forms a vortex air current in dust collecting receptacle 130 , and then is discharged to connection hose 103 ′′ via discharge outlet 111 a.
- Dust collecting receptacle 130 is positioned along side of connection pipe 112 b.
- Connection pipe 112 b of the present invention has a cross-sectional profile that matingly accommodates the cross-sectional geometry of receptacle 130 along at least a portion of its length. As shown in FIG.
- connection pipe 112 b which is proximate dust collecting receptacle 130 has a shape corresponding to the outer surface of dust collecting receptacle 130 so that these two pieces are fitted closely together along their coextensive portions. More specifically, dust collecting receptacle 130 , in cross-section, is substantially circular, while the side of connection pipe 112 b that extends alongside is contoured substantially in the shape of an arc to form a concave surface that geometrically mates with the receptacle wall. Since connection pipe 112 b and dust collecting receptacle 130 are in tight contact with each other due to these respective structural characteristics they form a more compact overall profile and thus occupy less space.
- connection pipe 112 b in a horizontal cross-section along most of the portion that it is coextensive with the receptacle is approximately a rectangular shape.
- connection pipe 112 b is cylindrical as shown in FIGS. 3 and 4 so as to be connectible to cylindrical extension pipe 103 ′.
- connection pipe 112 b is designed such that the rectangular portion thereof transitions smoothly into the cylindrical portion.
- a handle 160 integrally formed on second member 112 of the cyclone body 120 , and designed to have the size and shape that are appropriate for a user to easily grip the same.
- Handle 160 provides a user with a convenient grip when he/she performs a vacuum cleaning operation or carries the cyclone dust collecting apparatus.
- the vacuum cleaner having the above-described cyclone dust collecting apparatus operates in a similar manner as the prior art vacuum cleaner described above in the Background section.
- the overall thickness of the combination of extension pipe 112 b and dust collecting receptacle 130 is reduced, and accordingly, the vacuum cleaner is easier to use.
- Geometrically mating the outer surfaces of extension pipe 112 b and receptacle 130 not only renders the apparatus more compact, but also provides an assembly guide surface along their contact areas for easy placement and assembly of the receptacle.
- an enhanced attachment is provided as the two elements have mating bearing surfaces, compared to the sole use of a fastener to join together two circular shapes along a single line as previously used instead of a surface.
- the structural features are provided to facilitate cleaning operation or easy transport of the cyclone dust collecting apparatus by provision of handle 160 provided thereon.
